Solve for p in the literal equation 4p + 3r = 9.

p=

p = - 3/4r+9

Step-by-step explanation:

1. Subtract 3r from both sides of the equation to isolate p on one side of the equation

a. 4p+3r - 3r = 9 - 3r

b. 4p=9-3r

2. Divide every term in the equation by 4

a. 4p/4=9/4 - 3r/4

b. p=9/4 - 3r/4

3. Rearrange the equation (if need be) into slope-intercept form.

a. p = - 3r/4 + 9/4

p = 9/4 - 3r/4

Step-by-step explanation:

Move 3r to the right and when you divide 4 from both sides and each variable, you are left with p = 9/4 - 3r/4 since you cannot simplify it more.
